Application filed February This invention relates to feed'roll-releasing mechanism in typewriting machines, and is particularly useful'in facilitating placing and fixing of bills in typing posi .ion, especially where a record-sheet is employed upon which to make carbon copies or entries of successive bills.

According to the invention, from the front of the platen and from any desired position along the platen, the operator may release the feed-rolls that run on the under side of the platen, and may also make said releasing operation constitute a part of the sheetcollating operation. The device includes a sheet-aligning bar or collating table extending along the platen, and hinged so as to be swung forwardly to cast off the feedrolls, and may be locked forward. Said aligning bar or collating table may be held in an intermediate position during the insertion of the work-sheet.

The work-sheet may be positioned for typing by means of the upper edge of the aligning 031.,RSS1S1Z8d by the fingers of the typist, or a ledge at the upper edge of said bar. To accommodate various lengths of bills, the ledge may be adjustably mounted on the bar, to act as a gage.

The aligning bar may be readily adjustable lengthwise of the platen.

Other features and advantages will hereinafter appear.

1n the accompanying drawings,

Figure 1 is an end elevation, partly in section, of the carriage and associated parts of a typewriting machine embodying the present invention, and showing the feedrolls in effective position.

Figure 2 is similar to Figure 1, but shows the feedrolls released during the insertion of a bill.

Figure 3 is a front elevation of the carriage, showing the feed-roll-releasing means and other parts.

Figure 4: is a fragmentary side elevation, partly in cross-section, showing an adjustable ledge mounted on the aligning bar.

Figure 5 is a diagrammatic front elevation of the device shown in Figure 4.

A platen by means of an aXle 11 is journaled in side plates 12 of a platen'frame, shiftable up and down by the case-shifting mechanism, including guide-link 9, usual in a standard Underwood typewriting ma chine. The usual rear paper shelf 13 has an 8, 1924. Serial No. 691,335.

apron extension 1 1 for guiding work-pieces down behind the platen 10 and around under the same to the printing line at the front thereof. Front feed-rolls 15 are on a shaft 17 seated on arms 18 of bell-crank levers pivotally mounted on a shaft 19. Rear feedrolls 16 are on a shaft 20 seated on arms21 of bell-crank levers also pivetally mounted on shaft 19. The bell-crank levers which comprise the arms 18 have other arms 22 which depend to the rear of a shaft 2%,. and the bell-crank levers which comprise the arms 21 have other arms 23 which depend to the front of the shaft 2 1. Leaf-springs 25 hearing against arms 18 and 21 tend to rock the arms upwardly to throw the feedrolls 15 and 16 against the platen 10, and, therefore, tend to press the arms 22 anc 28 against the shaft 2 1. Shaft 2 1 has flats 26 cut thereon where the arms 22 and 23 engage the same. When the feed-rolls l5 and 16 are in effective position, the arms 22 and 23 stand slightly free of the flats 26, as shown in Figure 1. lVhcn, however, the shaft 2% is rotated, the arms 22 and 23 are forced apart to draw down the feed'rolls 15 and 16, as shown in Figure 2. The shaft 2 1 is journaled in the hanger-plates 31 supported from shaft 19. The feed-roll mecha nism, just described, is that found on the standard Underwood typewriting machine. The feed-rolls 15 and 16'may be thrown off the platen 10 by means of a release-control-device 32 besides the usual release-control lever-key 33 through the following interconnecting parts. Fast to the shaft 24 is an arm 34.- which is connected at one end to a link 85, which is connected to a cranklever 36 having a rigid stub-shaft 37, mounted between the right-hand side plate 12 of the platen-frame and a side bracket 38 and mounted on the outer end of the stub-shaft 37 is the lever-key 33 as shown in Figure 3. The release controhdevice 32 may comprise the rod 38 extending over the platen 10 and running lengthwise thereof. Rod 38 is fastened at each end to supporting arms 39, the free ends of which are pivoted at 39 on downwardly-extcnding members 10 mounted on and extending from the front topportion of the platen-frame side pieces 12. An aligning bar 11 which is in effect a collating table also serves as a handle for the control-device 32 and may be mounted to move with the rod 38 by means of widely spacedbrachet arms 42 fastened to :the bar 1 41 and slidingly embracing the rod 38.

Rod 38 may be provided with a flattened surface 43 extendinglengthwise thereof, and

ing idown a-from the -free end thereof, in

which may roclzha eo-operating pin 49securediin the .right hand swingahle supportarm 39.

" In the drawings, a record-sheet 50 faced hvlra carbon-sheet 51, is shown as having been fed downthe table "13 and-around the platenllO, and ashavlinga typed portion thereozf.extending-rearward over the-top of theiplaten 10. The irecord sheet ;-50 receives the entries made snccefssivelyupfin series or" individual short sheets or cards, ;hills '91 statement-sheets 46, ,and, ,in jOZftlSl that the record-sheet '50 may-beheld in place aipon V :the platen .10, While the-teed-rolls :1? and 16 are released for tinsel-ting or removing b lh sheets '46, vusual downvvardlyeextend ng rfingers or clips, carrying rolls supported above the platen 410, may :be provided. These fingers {are not shown but the :rolls are indicated inzthe dotted-lines at "In .typing "on well-known work piece forms comprising a card, statement er bill sheet x46, -which. isr-to he inserted giro n the affront of the machine against ,recordsheet 130 .onpthetplaten .10,.gthe recerd sheet 50 and :thericarbonl are first fed-around -tlie,;platen '10 :to typing position, while [the teed-rolls and zltifarein effective position, by means of v the hand-wheels -53 on platenaxle 11, or by the usual line-spacing mechanism, including ;the line space (wheel 53*.

As the bar 41 is thusae-tuated, git causes theipin 49 on -the-supporting arm 3939 1 001: arm 47, which, in turn, operates the feedroll releasing'gnechanism,to throw the feedrolls 15 and 1,6 Qfi ;the platen 10, permitting the insertion of. the lower edgeof th-e hillsheet'46-around the platen 10 between the latterand the apron 14 (see EigureQ). ,The

in Figure 2. Bar 41 may then be restored to its initial position, permitting springs to throw --feed-rolls 15 and 16 toward the platen 10, for holding the bill-sheet 46.

Figure 2 shows the aligning bar 41 in its extreme torwardly-moved position for releasahly v.locking ;g the .feed-rollsrlfi and .16 away from the platen "10, but eitais obvious that the bar 41 may be moved toanintermediate position, in whichicase, uponthe ,removal of the finger of the typist from the bar .41, the control-deviceparts will;.automatically be restored to their normal ef-v fectiye position. After the typingjofa-ibillsheet..46 is completed, the carriage i-is'thrown rightward for commencement of writingon another statement-sheet. The lever not hown), by which the carriageis gthus {1T8- turned, 7 ordinarily effects a single line-space movement oi the platen 10'by'ga mechanism not here-shown. This results inaline-space movement of the record-sheet and the carbon 51, sons to prepare-the same :for re ceiving the entry to be nade on the next succeeding bill sheet 4". The hill-sheet .46 in the machine may be removed afte-nthabar 41 is drawn forward and another inserted 'as described above. 7

Instead of positioning the hill-sheet 46, for typing, on ;,the aligning bar/41,,assisted by :the fingers of the typist, an adjustable ledge or gage 5?" may he ,mounted on the bar .ifor e om cdati s re u' len h e hil sheets and for aiding the ba-rAflto-position the bill-sheet 46. The gage ;,57 :,ni ay be formed or a forwardly-extending shoulderpiee 8 ormingsmeeqf ith a p e ed of the bill-sheet 46, and downwardly ,bent

from said shoulder-58"may-be spaced .arms{54v adjustabl-y mounted on {the bar. 41 by uneans o1"- thumb-screws 55 passingthrough slots 56 in the arms 54and threadediintov-the bar .41, i as shown in Eigures 4 .and 5 it will be understoodthat theresend-sheet andthe carhonsheet may beadjustederound the platen fwhileirthe teed-rolls are released, and that these sheets may be held in-positionby-the rolls/ 52 of the paper-lingers. It will further ibe' understood ,th-at the-first bi11-sheet 46 may be inserted ,ar lllld :the

platen from. the back, i and then adjusted, as

above described, :to the printing point, after which the iced-rolls may he Ethrown OII' tO. hold allot the sheetsqon the, platen. T he succeeding-billesheets 46 may each :be ,inserted from the front of the platen after the feed rqlls have been released, and prior to the removal of :thepreceding bill-sheet,

the latter serving asa means to guide the fresh or untyped bill-sheet around the ,platen.

Pivots 39 are preferably arranged in alignment with the position of the printing line on platen 10, so that the distance from the printing line to the, upper edge of the bar ll is always the same, thus avoiding-any possibility of shifting the printing line on the bill-sheet 46 with respect to the position of the printing line on platen 10 when swinging the bill-sheet 46 with thebar ll from the position shown in Figure 2 to that shown in Figure 1. y

The above description explains the operation of a typewriting machine embodying the invention for typing a relatively complex work-piece. It is obvious that simple and ordinary forms may be typed with equal advantage by the use of the same.

The bill-sheet'may be held, or, in other words, may be prevented from unnecessarily falling forward, by a finger 60, which may be supported on the usual front bar (not shown) of the carriage-frame. The linger may be so supported that it may be conveniently swung out of the way while in serting a fresh bill.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others Having thus described my invention, I claim: l y
